An analysis of the Diablo Canyon Power Plant Radiological Environmental Monitoring Program sampling results from the Cal Poly, San Luis Obispo, dairy herd milk, post-Fukushima

Creator:: Treinen, Richard M.
Abstract:: This study focuses on iodine-131 detected in milk samples from the Dairy Science Unit at Cal Poly, San Luis Obispo, California following events at the Fukushima Dai-ichi Nuclear Power Plant in March of 2011. The samples were collected as part of the Diablo Canyon Nuclear Power Plant (DCPP) Radiological Environmental...

Detection of Dual Heterodera avenae Resistance plus Tolerance Traits in Spring Wheat

Creator:: Smiley, Richard W. and Marshall, Juliet M.
Abstract:: The cereal cyst nematode Heterodera avenae reduces wheat yield in the Pacific Northwest. Resistance and tolerance traits among spring wheat cultivars were poorly defined. Screening trials were conducted with 39 cultivars over a 2-yr period in irrigated commercial fields that were infested by H. avenae. Comparisons were made between drill...

Spring Barley Resistance and Tolerance to the Cereal Cyst Nematode Heterodera avenae

Creator:: Marshall, Juliet M. and Smiley, Richard W.
Abstract:: Heterodera avenae is a cereal cyst nematode that reduces wheat yields in the Pacific Northwest USA. Barley is also susceptible but there were no previous reports of resistance or tolerance to H. avenae in the USA. Spring barley cultivars were assayed in H. avenae-infested fields over two years. Cultivars were...

Noble gases and coupled heat/fluid flow modeling for evaluating hydrogeologic conditions of volcanic island aquifers

Creator:: Heilweil, Victor M., Healy, Richard W., and Harris, Robert N.
Abstract:: Understanding groundwater conditions in the upland parts of volcanic island aquifers is critical for sustainable groundwater development in these resource-limited environments. Yet groundwater conditions in such settings are generally difficult to characterize because of sparse well drilling (high cost and/or limited access). Information needed for resource evaluation includes upland depth...

Long-term Outcomes of Military Service in Aging and the Life Course: A Positive Re-envisioning

Creator:: Spiro, Avron, III, Settersten, Richard A., and Aldwin, Carolyn M.
Abstract:: Most research on military service focuses on its short-term negative consequences, especially the mental and physical injuries of those deployed in warzones. However, studies of long-term outcomes reveal surprisingly positive effects of military service—both those early in adulthood that grow over time and others that can emerge later in life....

Climate change, water rights, and water supply: The case of irrigated agriculture in Idaho

Creator:: Xu, Wenchao, Lowe, Scott E., and Adams, Richard M.
Abstract:: We conduct a hedonic analysis to estimate the response of agricultural land use to water supply information under the Prior Appropriation Doctrine by using Idaho as a case study. Our analysis includes long‐term climate (weather) trends and water supply conditions as well as seasonal water supply forecasts. A farm‐level panel...

Comparison of Disturbed and Undisturbed Soil Core Methods to Estimate Nitrogen-Mineralization Rates in Manured Agricultural Soils

Creator:: Moberg, Dean P., Johnson, Richard L., and Sullivan, Dan M.
Abstract:: Ion exchange resin/soil cores are a common in situ approach to estimating soil nitrogen (N) mineralization rates. However, no studies compare the two common methods of core preparation (disturbed and undisturbed). The objective of our study was to compare N mineralized and soil temperature in disturbed versus undisturbed cores of...

Subducted seamounts and recent earthquakes beneath the central Cascadia forearc

Creator:: Tréhu, Anne M., Blakely, Richard J., and Williams, Mark C.
Abstract:: Bathymetry and magnetic anomalies indicate that a seamount on the Juan de Fuca plate has been subducted beneath the central Cascadia accretionary complex and is now located similar to 45 km landward of the deformation front. Passage of this seamount through the accretionary complex has resulted in a pattern of...

Utilizing Fishermen Knowledge and Expertise: Keys to Success for Collaborative Fisheries Research

Creator:: Yochum, Noelle, Starr, Richard M., and Wendt, Dean E.
Abstract:: Collaborative fisheries research provides a mechanism for integrating the unique knowledge, experience, and skills of fishermen and scientists. It is a joint intellectual endeavor that begins with the inception of a project and continues until its final stages, with each group having mutual investment in-and ownership of-the project. Collaborative fisheries...

Constancy and change in marine predator diets across a shift in oceanographic conditions in the Northern California Current

Creator:: Gladics, Amanda J., Suryan, Robert M., Brodeur, Richard D., Segui, Leah M., and Filliger, Laura Z.
Abstract:: Variable ocean conditions can greatly impact prey assemblages and predator foraging in marine ecosystems. Our goal was to better understand how a change in ocean conditions influenced dietary niche overlap among a suite of midtrophic-level predators. We examined the diets of three fishes and one seabird off central Oregon during...
